# Plotje

Composable plotting in Clojure

![](readme_files/image0.svg)

---------------------

Plotje is a Clojure library for composable plotting, inspired by

the Grammar of Graphics.

## Usage

Add to your `deps.edn`:

```clojure

org.scicloj/plotje {:mvn/version "0.1.0"}

```

Several core dependencies (kindly, fastmath, clojure2d, membrane,

wadogo) are still on alpha or beta channels. Adopters may need

to ride those alpha-channel transitives until they cut stable

releases.

Plotje is intended to be used with data-visualization tools

that support the [Kindly](https://scicloj.github.io/kindly) convention

such as [Clay](https://scicloj.github.io/clay/).

## Quick example

Line chart with point markers from plain Clojure data:

```clj

(-> [{:month "Jan" :sales 120}

     {:month "Feb" :sales 95}

     {:month "Mar" :sales 140}

     {:month "Apr" :sales 175}

     {:month "May" :sales 160}

     {:month "Jun" :sales 210}]

    (pj/lay-line :month :sales)

    pj/lay-point

    (pj/options {:title "Monthly Sales"}))

```

Scatter plot matrix (SPLOM) — all pairwise combinations with color grouping:

```clj

(-> (rdatasets/datasets-iris)

    (pj/pose (pj/cross [:sepal-length :sepal-width

                        :petal-length :petal-width]

                       [:sepal-length :sepal-width

                        :petal-length :petal-width])

             {:color :species})

    (pj/options {:title "Iris SPLOM"}))

```
